About the research

Speed feedback signs are used in a variety of situations. They have been implemented in work zones, school zones, and along residential or commercial locations. Their impact on speeds have generally been shown to be a reduction from one to ten miles per hour. These sign installations can be portable or permanent and either post-mounted or trailer-based.

This project includes an investigation into the need and potential use of a speed feedback sign loan program by local agencies, the type of signs that would be of value to these agencies, the ongoing costs of such a program, and the acquisition and loaning of speed feedback signs. The signs purchased, when not in use by local agencies, could also be used for data collection and evaluation purposes by Institute for Transportation (InTrans) and Department of Transportation (DOT) staff.

It is currently proposed that these signs be acquired and, if appropriate, incorporated into the Iowa LTAP equipment loan program. Another possibility is they could be part of another program at InTrans. A determination of the program structure will be based on the results of completed project tasks.

The primary objective is to develop a speed feedback sign loan program in a manner that is used by local agencies, sustainable in its operation, and makes the speed feedback signs as easily available to local agencies throughout Iowa as possible.
